This bug is fixed for the next version 19.02 due by end of February. It was a bug in regions that use a comma for the decimal point. The main workaround until then is to use keyframes to slightly alter the position every 2 or so frames.
Yet another is to make a copy of the preset file in the same folder with your own name. Then, open the preset in a text editor and change all the periods in the number values to commas.
